The only problem would be getting the robots to let go of control, once the humans arrive.

A friend of mine working in a lab with rats, told me that rats live a very comfortable life there, at least until they are "used", arguably more comfortable than rats living in the wild. I know, this is not exactly a valid excuse.

Not sure if you mean tuning each mirror, but as a minimum I expect the whole structure to rotate during the day to follow the sun, or you'd waste a lot of its potential.
